Containerization has transformed the way teams build, package, deploy, and manage software. In this video, we break down what containerization is, how it works, and why it has become the standard for modern application delivery.

You’ll learn how containers package applications with all their dependencies, making them portable, consistent, and easy to run across any environment. We explore the key benefits of containerization — including scalability, reliability, performance, and security — as well as how developers use containers to speed up development and collaboration.

We also cover the technologies behind containerization, including Docker, container engines, and orchestration platforms like Kubernetes. You’ll see how containerization compares to virtualization, and why containers are lighter, faster, and more efficient.

Finally, we look at how Harness integrates with container platforms and orchestration systems to create containerized pipelines, simplify builds, eliminate dependency issues, and accelerate software delivery.
